Lab Director


Florian Willomitzer is a Research Assistant Professor in the Department of Electrical and Computer Engineering (ECE) at Northwestern University, IL. He graduated from the University of Erlangen-Nuremberg, Germany, where he received his Ph.D. degree in Physics with honors (‘summa cum laude’) in 2017. During his doctoral studies (PhD advisor: Prof. Gerd Häusler) Florian investigated physical and information theoretical limits of optical 3D-sensing and implemented sensors that operate close to these limits. Concurrent with his Ph.D. activity, he was a freelancer in the research group’s spin-off company ‘3D Shape GmbH’ (now part of ISRA Vision) and he worked as a high school part time teacher for physics. Florian joined Northwestern University as Postdoc (Postdoc advisor: Prof. Oliver Cossairt) in Fall 2017, where he further shaped his current research profile. He became Research Assistant Professor in 2019.

Florian is General Chair of the OSA COSI conference, Optics Chair of the IEEE ICCP conference, Committee member of the OSA FiO conference, and served/serves as reviewer for IEEE, OSA, SPIE, CVPR, and the Nature Portfolio. He is a recipient of the NSF CRII grant and his Ph.D. thesis was awarded with the Springer Theses Award for Outstanding Ph.D. Research.

He is currently teaching the courses ‘CS331: Introduction to Computational Photography’, ‘EE420: Digital Image Processing’, and ‘EE395/495: Computational Photography Seminar’.


PhD Students


Manuel Ballester is a doctoral candidate at Northwestern University and a member of the 3DIM lab led by Prof. Willomitzer. His research applies novel optimization techniques, advanced computational methods, and machine learning approaches to optics and imaging problems. He works on synthetic wavelength imaging and the improvement of holographic displays. He is also interested in the material characterization of semiconductors (such as CZT and Silicon) to improve sensor performance.

Manuel completed his BSc in Mathematics in 2018 at the University of Cadiz. He received an MSc in Optical Physics in 2021 at the University of Erlangen-Nuremberg.

Aniket Dashpute is a PhD student in the Electrical Engineering Department at Northwestern University. His current research includes using Event Cameras for 3D shape measurement and applying Computational Imaging techniques to Thermal Imaging & Rendering. He is also interested in Neural Rendering and its applications to computational photography. Aniket completed his undergrad in EE at the Indian Institute of Technology Delhi (IIT D), India in 2018 where he was advised by Prof. Kedar Khare. He then worked in Samsung Research Institute Bangalore, India till 2020 in the Computer Graphics team responsible for rendering and visualising medical ultrasound data.

Jiazhang Wang is a Ph.D. candidate in the Department of Electrical and Computer Engineering (ECE) at Northwestern University. Before joining Northwestern, he earned his master’s degree in Electrical Engineering from Columbia University and bachelor’s degree in Electrical Engineering from Huazhong University of Science and Technology (HUST). His research interests include computational photography, 3D optical metrology and computer vision. He is currently working on developing a novel eye-tracking prototype using optical metrology.
